What is a Legionella Risk Assessment?
Before we dive in, let’s clearly define what a Legionella risk assessment is. Legionella is a type of bacteria that can develop in water systems such as tanks, pipes, showers, and taps. If inhaled through small droplets of contaminated water, it can lead to Legionnaires’ disease, a serious form of pneumonia. A Legionella risk assessment is a detailed inspection of a property’s water systems to identify potential risks of Legionella bacteria growth. The purpose of a Legionella risk assessment is to:
- Identify potential sources of Legionella bacteria
- Assess who may be at risk
- Evaluate the condition and management of water systems
- Recommend control measures to reduce or eliminate risk
Why are Legionella Risk Assessments Important?
For any occupied property with access to a water system, Legionella risk assessments play a vital role in safeguarding the health and safety of its occupants. Whether it is a rented home managed by a landlord or a busy office building managed by a facilities manager, water systems must be maintained and assessed in line with UK regulations. Without proper monitoring and control, this can pose a significant health risk. A professional assessment ensures that:
- Risks are identified early.
- Control measures are implemented.
- Legal responsibilities are met.
At Absolute Property Surveys, we carry out thorough Legionella risk assessments to help property owners understand their systems and take appropriate action. Beyond the essential health and safety considerations, there are several pieces of UK legislation that make Legionella risk assessments mandatory. These include:
- Health and Safety at Work Act (1974)
- Management of Health and Safety at Work Regulations (1999)
- Control of Substances Hazardous to Health Regulations (2002)
Failure to remain compliant also comes with considerable consequences for the building or business owner, including:
- Enforcement action by the HSE
- Prosecution under HSWA (Health & Safety at Work Act) or COSHH (Control of Substances Hazardous to Health Regulations)
- Significant fines
- Increased liability following illness or outbreak
What is ACOP L8, and How Does it Apply to Legionella Risks?
ACOP L8 is an Approved Code of Practice published by the UK’s Health and Safety Executive (HSE). Although it is not legally mandated, it provides important guidance on how to comply with legal requirements when managing Legionella risks in your premises. According to ACOP L8, duty holders should:
- Carry out a Legionella risk assessment
- Appoint a competent person
- Implement a written scheme of control
- Monitor and maintain water systems
- Keep records and review the assessment regularly
How Often is a Legionella Risk Assessment Required?
A common question is, “How often are Legionella risk assessments required?” For property managers, Legionella risk assessments are typically recommended every two years, with regular reviews to ensure they remain valid. If your Legionella risk assessment is due for review, contact our team today to arrange your free quote or book an appointment. There are also instances where you should consider carrying out an additional Legionella risk assessment, including:
- When there are changes to the water system
- If the property use changes
- If there are concerns about water quality or safety
Ultimately, how often a Legionella risk assessment should be carried out depends on both UK guidance and the specific condition and use of the property.
What Does a Legionella Risk Assessment Involve?
A professional Legionella risk assessment will usually include:
- A full inspection of the property’s water systems
- Identification of risk areas, such as dead legs or unused outlets
- Temperature checks to ensure water is stored safely
- Assessment of current control measures
- A detailed report with findings and recommendations
